摘要

摘要: 设计了一种聚甲基丙烯酸甲酯(PMMA)基的单偏振单模(SPSM)微结构聚合物光纤(MPOF)。利用全矢量有限元法和光束传播法相结合分析了这种光纤的偏振特性和约束损耗。通过优化光纤结构参数，发现在0.51 m～0.62 m的可见光波长范围，由于基模两个正交偏振模的截止波长不同，这种微结构聚合物光纤只能传输基模中的一个偏振模，从而实现单偏振单模运转。该11圈圆空气孔六角排列光纤结构的传导偏振模在0.57 m波长处约束损耗仅为1.13 dB/m，这种低损耗的单偏振单模微结构聚合物光纤可有效消除传统保偏光纤固有的偏振串扰和偏振模色散。

Abstract: The single-polarization single-mode (SPSM) micro-structure polymer optical fiber (MPOF) was designed based on polymethyl methacrylate (PMMA). A full vector finite element method together with beam propagation method was adopted to study the SPSM properties. By optimal designing, we found that only one polarization state of the fundamental mode could be transmitted within the visible light region from 0.52 m to 0.63 m according to the different cutoff wavelengths of the two orthogonal polarization modes. For MPOF with 11 rings of hexagonally arrayed air-holes, the confinement loss of 1.13 dB/m was obtained at 0.57 m. This low loss SPSM-MPOF can greatly eliminate the polarization crosstalk and polarization mode dispersion.
